You can use lighthouse

Chrome extension and it will tell you what that is

its pointing out to that section where my name loads in, do you think the way its loading like appearing like that is making that issue ? if thats the case what are the downsides of leaving it like that would it impact seo ?

Cumulative shift is when your page shifts around content after its been loaded aka the user can see something on their screen, so like for example an image resizing, text becoming big as the css renders etc.

Its bad cause it causes the page to move around

this is also a major CLS offender: when it loads it shifts the paragraph above it upwards significantly. but yeah just refer to google lighthouse, it will tell you all about this

yea i fixed it it was because i set the width and hight of the Image componenet to 0 and then i used the style attribute, the right way to do it is to set a fixed width and height, this comes at a tradeoff of responsiveness but i guess its all fixed now, thank you for helping me out!
